Description
The cross reference of related application
The application based on and require the priority of the Japanese patent application No.2008-159560 formerly that submitted on June 18th, 2008, the full content of this application is by reference in conjunction with in this application.
Technical field
The present invention relates to a kind of from the tissue echo-signal extract the small structure in the organism internal organs and diagnostic ultrasound equipment that shows and ultrasonography adquisitiones.
Background technology
Utilize ultrasonic diagnosis,, just can obtain the sample attitude of heartbeat or F/A in the mode of real-time demonstration by ultrasound probe being contacted the such shirtsleeve operation of body surface.In addition, because ultrasonic diagnosis is safe, so can carry out inspection repeatedly based on ultrasonic diagnosis.And the scale of diagnostic ultrasound equipment is littler than other diagnostic equipments such as X ray, CT, MRI.Therefore, can move to bedside to diagnostic ultrasound equipment at an easy rate and check etc., we can say that ultrasonic diagnosis is a kind of easy diagnostic method.
Diagnostic ultrasound equipment is had nothing in common with each other according to the kind of the function that it possessed.As small-sized diagnostic ultrasound equipment, a kind of needs the diagnostic ultrasound equipment of the singlehanded size that just can withdraw just under development.In addition, there is radiation effect in ultrasonic diagnosis unlike X ray, so also can be applied in obstetrics or the family therapy etc.
Have one of ultrasonic diagnosis of above-mentioned all strong points, comprise early diagnosis breast carcinoma.Known in breast tissue, as the symptom of breast carcinoma, often produce microcalciffcation.The microcalciffcation pathological changes is dispersed in the part one or morely.Because the hardness ratio bio-tissue height of Calx, so reflection supersonic wave more strongly.Therefore people expect that the microcalciffcation pathological changes presents high brightness on image.But actual detecting by an unaided eye during image is even hundreds of microns degree also is difficult to find the microcalciffcation pathological changes.
And, on ultrasonography, produce because hyperacoustic random disturbances interference fringe that cause, that be known as speckle pattarn sometimes.This speckle pattarn utilizes in the diagnosis of liver cirrhosis etc.
On the other hand, this speckle pattarn is quite similar with the small structures of for example omitting easily under the situation that above-mentioned breast carcinoma is checked such as microcalciffcation, becomes the difficult image information of differentiating for diagnosis sometimes.Therefore, in breast cancer diagnosis, there is the demand of removing speckle.
In view of the foregoing, for example space compound, CFAR (Constant FalseAlarm Rate: constant false alarm rate) technology such as processing, similarity filtration have been proposed.Here, space compound is meant overlapping and speckle is carried out level and smooth processing from the transmission received signal of different directions.CFAR handles, and is meant subject pixels is carried out subtraction with average brightness on every side, and extracts the processing of hi-lite with it.Similarity is filtered, and is meant and utilizes its statistics character, the processing of removing speckle.Except the method that these speckle pattarns are removed,,, reported the trial of various automatic identification microcalciffcations mainly as the application of radiodiagnosis image though do not belong to the field of ultrasonic diagnosis.
Yet the complex structure as the latex dust of the mammary gland of diagnosis object etc. does not just belong to homogeneous internal organs originally.If therefore carry out filtration treatment in the past, then when checking out microcalciffcation, the mammary gland structure also can be extracted out as structure, can't fully the two be made a distinction.
But, because latex dusts etc. are the obvious structures bigger than microcalciffcation, so, also can with the naked eye distinguish out even after filtration treatment, have remainingly sometimes.But the invention people also often run into so very situation of difficult of distinguishing under study for action.When particularly only remaining a part of mammary gland is constructed, can see that the image after the filtration treatment is point-like, so remaining sometimes mammary gland is constructed to manifest similar to microcalciffcation.
And, the speckle pattarn random fluctuation on the image sometimes.Even the speckle of being scheduled in this case suppresses to handle, speckle still has remaining, remaining speckle and the microcalciffcation position is difficult to distinguish.
In view of the foregoing, for example in TOHKEMY 2007-313114 communique, following technology has been proposed.Promptly, in TOHKEMY 2007-313114 communique, a kind of diagnostic ultrasound equipment is disclosed, it is characterized in that, possess: by the Flame Image Process of carrying out the 1st ultrasonography and extracting small structure based on the 2nd ultrasonography that the position of the 1st ultrasonography determines, promptly at each pixel on above-mentioned the 1st ultrasonography, the small structure that max pixel value in the reference area that is included in pixel corresponding on the space in above-mentioned the 2nd image is carried out difference extracts processing, and generates the Flame Image Process parts that small structure extracts image; With the display unit that above-mentioned small structure extraction image is shown in a predetermined manner.
The disclosed diagnostic ultrasound equipment of this TOHKEMY 2007-313114 communique provides following diagnostic ultrasound equipment: in the signal processing that extracts small structure, be not to utilize aspect of layer image, but utilize space three-dimensional information to carry out signal processing, for example can correctly distinguish small structure such as structure and microcalciffcation part continuously such as mammary gland, and extract small structure.
Employed ultrasound probe in the disclosed technology of TOHKEMY 2007-313114 communique is the device that can carry out ultrasonic scanning to the 3D region of subject.Therefore, employed ultrasound probe in the disclosed technology of TOHKEMY 2007-313114 communique, be to make ticker, 3D region carried out the ultrasound probe (being called as mechanical type 4D ultrasound probe) of the structure of ultrasonic scanning along mechanically shaking with the perpendicular direction of its orientation; Utilize the two-dimension vibration element of two-dimensional arrangements, 3D region is carried out the ultrasound probe (being known as real-time 3D ultrasound probe) of the structure of ultrasonic scanning etc. by electric control.
